Problems solved by technology

[0009] The paper clays of the above-mentioned related patents can be used as sculpture materials. They contain pulp in common, but their density is relatively high, and the products are heavy. They appear to be cumbersome, sticky, and unclean during the sculpture production process.
Plasticine also has the disadvantages of being sticky and unhygienic, and there will be safety hazards for children during play

preparation example Construction

[0045] A preparation method of ultra-light paper clay, comprising the following steps:

[0046]1) Boil water and viscous material according to (5-10): 1 mass ratio to form basic cohesive material, and take 20-75 parts by mass;

[0047] 2) Select the filler, and crush the filler into particles of suitable size, and take 10-70 parts by mass;

[0048] 3) The plant fiber is subjected to beating or refining treatment until the plant fiber becomes soft and cut and divided;

[0049] 4) After the cross-linking agent is completely dissolved, add it to step 1) and stir evenly;

[0050] 5) Add the crushed filler in step 2) and the treated plant fiber in step 3) to step 1), mix well and heat to form a mud-like product; the mixing process and heating in step 5) are at the same time To carry out, the heating temperature is 60-100°C, so as to keep the bonding material in an easy-to-flow state, reduce the stirring resistance, and avoid the phenomenon of uneven stirring.

[0051] 6) Add 0.8...

Embodiment 1

[0056] 1) Boil water and viscous material according to the mass ratio of 5:1 to form the basic bonding material, and take 20 parts by mass; the boiling time is 0.5 hours, and the boiling temperature is 60°C.

[0057] 2) Select the filler and crush the filler, wherein the particle size of the crushed particles is 10 mesh, and take 70 parts by mass;

[0058] 3) The plant fibers are beaten or refined until the plant fibers become soft and cut and divided into filaments to make them better mixed and improve the cracking of the product; the mass fraction of water in the plant fibers is 40% .

[0059] 4) After the cross-linking agent is completely dissolved, add it to step 1) and stir evenly;

[0060] 5) Take 1 portion of the crushed filler in step 2) and the treated plant fiber in step 3) and add it to step 1), and mix well to form a mud-like product; the mixing process in step 5) It needs to be completed in a heated state, and the heating temperature is 60°C, so as to keep the b...

Embodiment 2

[0065] 1) Boil water and viscous material according to the mass ratio of 8:1 to form the basic bonding material, and take 40 parts by mass; the boiling time is 2 hours, and the boiling temperature is 80°C.

[0066] 2) Select the filler and crush the filler, wherein the particle size of the crushed particles is 500 mesh, and take 35 parts by mass;

[0067] 3) The plant fibers are subjected to beating or refining treatment until the plant fibers become soft and cut and divided into filaments to make them better mixed and improve the cracking of the product; the water content in the plant fibers is 70%.

[0068] 4) After the cross-linking agent is completely dissolved, add it to step 1) and stir evenly;

[0069] 5) Add 9 parts of the crushed filler in step 2) and the treated plant fiber in step 3) to step 1), and mix well to form a muddy product; the mixing process in step 5) It needs to be completed in a heated state, and the heating temperature is 80°C, so as to keep the bondi...

Abstract

The invention discloses ultralight paper clay and a preparation method thereof. The preparation method comprises the following steps: adding a plant fiber raw material t0 a binder serving as a base material, and mixing with raw materials with specific effects, to produce novel paper clay which is soft and extremely good plasticity, wherein the novel paper clay is purely white in primary color, various non-toxic pigments are added during the preparation process to obtain paper clay of multiple colors, or the surfaces of formed objects can be dyed into various colors. The paper clay has the properties of a common kneaded-moulded material and has ultralight mass which is about one half of the specific gravity of water, and moreover the dry weight of the paper clay can reach a quarter of the wet paper clay. Besides, the raw materials adopt non-toxic and natural materials, thus having no harm to a human body, especially avoiding contact harm to children during playing.

Description

technical field [0001] The invention relates to an ultra-light paper clay and a preparation method thereof. The ultra-light paper clay is used to replace the original ordinary clay, clay, sand, plasticine, etc., and can be used for education, games, kneading works, paintings, etc. Background technique [0002] At present, most of the materials used for kneading or painting on the market are traditional paper clay or traditional soft sculpture materials such as plasticine, soft pottery, flour mud, sand, etc., which are not only heavy in texture, high in greasy, unhealthy and unhygienic, but also Preservation is also more difficult, and more importantly, they are all chemical materials, not only cannot be reused, but also difficult to recycle, which is harmful to environmental protection. [0003] The Chinese invention patent with the patent number CN 1057249A provides a kind of "paper clay as a sculpture lining". The present invention uses 60% clay from Yuci, Shaanxi or Suzho...
